Weizman goes on to interview a commander of the Israeli Paratrooper Brigade. The commander describes his forces as acting “like a worm that eats its way forward, emerging at points and then disappearing. We were thus moving from the interior of homes to their exterior in a surprising manner and in places we were not expected, arriving from behind and hitting the enemy that awaited us behind a corner.”

This is how the troops could “adjust the relevant urban space to our needs,” he explains, and not the other way around.

Indeed, the commander thus exhorted his troops as follows: “There is no other way of moving! If until now you were used to moving along roads and sidewalks, forget it! From now on we all walk through walls!”

…

In fact, I’m reminded of a scene toward the end of the recent WWII film Days of Glory in which we see a German soldier blasting his way horizontally through a house, wall by wall, using his bazooka as a blunt instrument of architectural reorganization—"adjusting the relevant space to his needs,“ we might say—and chasing down the French troops without limiting himself to doors or stairways.

In any case, post-battle surveys later revealed that "more than half of the buildings in the old city center of Nablus had routes forced through them, resulting in anywhere from one to eight openings in their walls, floors, or ceilings, which created several haphazard crossroutes"—a heavily armed improvisational navigation of the city.

So why do I mention all this in the context of Die Hard? The majority of that film’s interest, I’d suggest, comes precisely through its depiction of architectural space: John McClane, a New York cop on his Christmas vacation, moves through a Los Angeles high-rise in basically every conceivable way but passing through its doors and hallways.

…

Over the course of the film, McClane blows up whole sections of the building; he stops elevators between floors; and he otherwise explores the internal spaces of Nakatomi Plaza in acts of virtuoso navigation that were neither imagined nor physically planned for by the architects.

His is an infrastructure of nearly uninhibited movement within the material structure of the building.

…

What I find so interesting about Die Hard—in addition to unironically enjoying the film—is that it cinematically depicts what it means to bend space to your own particular navigational needs. This mutational exploration of architecture even supplies the building’s narrative premise: the terrorists are there for no other reason than to drill through and rob the Nakatomi Corporation’s electromagnetically sealed vault.

Die Hard asks naive but powerful questions: If you have to get from A to B—that is, from the 31st floor to the lobby, or from the 26th floor to the roof—why not blast, carve, shoot, lockpick, and climb your way there, hitchhiking rides atop elevator cars and meandering through the labyrinthine, previously unexposed back-corridors of the built environment?

Why not personally infest the spaces around you?

…

For example, Weizman outlines what the Israeli Defense Forces call "hot pursuit"—that is, to "break into Palestinian controlled areas, enter neighborhoods and homes in search of suspects, and take suspects into custody for purposes of interrogation and detention.” This becomes a spatially extraordinary proposition when you consider that someone could be kidnapped from the 4th floor of a building by troops who have blasted through the walls and ceilings, coming down into that space from the 5th floor of a neighboring complex—and that the abductors might only have made it that far in the first place after moving through the walls of other structures nearby, blasting upward through underground infrastructure, leaping terrace-to-terrace between buildings, and more.

…

If Jason Bourne’s actions make visible the infrastructure-rich, borderless world of the EU, then John McClane shows us a new type of architectural space altogether—one that we might call, channeling topology, Nakatomi space, wherein buildings reveal near-infinite interiors, capable of being traversed through all manner of non-architectural means. In all three cases, though—with Bond, Bourne, and McClane—it is Hollywood action films that reveal to us something very important about how cities can be known, used, and navigated: these films are filled with the improvisational crossroutes that constitute Eyal Weizman’s “Lethal Theory.”

…

On the other hand, as Weizman points out, this is not a new approach to built space at all:

“In fact, although celebrated now as radically new, many of the procedures and processes described above have been part and parcel of urban operations throughout history. The defenders of the Paris Commune, much like those of the Kasbah of Algiers, Hue, Beirut, Jenin, and Nablus, navigated the city in small, loosely coordinated groups moving through openings and connections between homes, basements, and courtyards using alternative routes, secret passageways, and trapdoors.”

This is all just part of “a ghostlike military fantasy world of boundless fluidity, in which the space of the city becomes as navigable as an ocean.”

Treated as an architectural premise, Die Hard becomes an exhilarating catalog of unorthodox movements through space.
